Hi, anybody can help us, please help with this, we can't start to use apache

1. install svn 1.2.3 on windows,
2. create a repository on c:/repositorio

3. install apache 2.0.55 on port 81 it's ok
 4. copy files mov_dav to modules on apache, it's ok
5. configure httpd the last lines is:

<Location /svn>
DAV svn
SVNPath c:/repositorio
</Location>

but when we go to the direction: http://localhost/svn the message is:
